Specification of Letters Patent.

Patented Dec. 29, li ht.

Application filed June 11, 1914. Serial N 0. 84 3,5 19.

To all whom it may concern Be it known that I, EDWARD S. STIMrsoN,

a citizen of the United States, residing at,

Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in F illing-Replenishing Looms, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to a means for preventing the operation of the filling re plenishing mechanism in an automatic loom upon the failure of the filling feeder properly to position a filling carrier or trans ferrer after the indication of entire or partial exhaustion in the running shuttle and the object is to provide a simple and efiicient means for securing this result, particularly by or through the restraining of the operation of a horizontally movable shuttle feeler when the filling feeder is improperly positioned, and also particularly by or through the agency of the detent pawl controlling the rotation and position of the feeder.

The nature of the invention will appear more fully from the accompanying description and drawings and will be particularly pointed out in the claims.

The drawings show so much of an ordinary automatic filling replenishing loom together with the parts constituting a pre ferred form of this invention as is necessary to an understanding of the invention.

In the drawings, Figure 1 is an end elevation and partial transverse section of a suflioient portion of an automatic filling re plenishing loom of the Northrop type with the parts involved in this invention applied thereto; Fig. 2 is a view partially in vertical cross section through the hopper or feeder showing parts concerned in the present invention; Fig. is a plan view partially trated and described in detail in the patent to Davis No. 1,091,813 granted March 31, 1914, and in view of the complete description and illustration of the mechanism of the loom and shuttle feeler contained in these two patents it will be unnecessary here to describe in detail anything more than those parts directly concerned with the present invention.

The breast beam of the loom 1 has fixedly mounted thereon the usual filling feeder which comprises two disks or plates 2 to re ceive, hold and position the spare filling carriers 3. The hopper stand 1 with its integral casing 5 inclosing the disk 2 is secured in the usual manner to the breast beam. The filling carriers or bobbins 3 are as usual held by their butts and tips by and between the two disks of the hopper or feeder in a circularly arranged series, the seats 6 for the butts being shown in Fig. 2. The filling carriers are brought one by one into position for transfer from the hopper or feeder to the running shuttle by suitable mechanism, such for example as that disclosed in the aforesaid patent to Stimpson No. 66%,790. This mechanism includes a toothed disk or ratchet wheel 7 rotatable with and located at the inner side of the disk 2 and having its teeth corresponding in number to the holding devices for the filling carriers, a dog 8 pivoted at 9 on the transferrer 10 and cooperating with the ratchet wheel 7, and a detent pawl 11 engaged between the teeth of the ratch t wheel 7. It will thus be seen that in the manner described in the Stimpson Patent No. 66%,790 upon movement of the transferrer 10 the feeder is rotated step by step to bring a filling carrier into position for transfer, and when the filling carrier is in proper position for transfer the detent pawl 11 will be seated in one of the notches of the ratchet wheel 7. This detent pawl is pivoted at 12 to the hopper stand, and its weighted foot 13 serves to hold it in engagement with the ratchet wheel.

The filling replenishing mechanism comprises the transferrer 10, already referred to, pivotally mounted at 14 on the hopper stand and operating when depressed or moved downwardly to transfer a filling carrier from the hopper or feeder to the shut tle. Atransferrer operating dog 15 as in the construction illustrated in the aforesaid patent to Davis No. 1,091,813 is pivoted at 16 to filling carrier and in] i will accordingly the depending arm 17 of the transferrer and moves in a horizontal direction guided by thehopper stand. A bunter 18 is pivot ally mounted at 19 to the lay 20 to cooperate with the transferrer dog.

The shuttle feelermechamsni is carried by by set screws 26 a guide bar 27 projecting rearwardly toward the lay. The shuttle feeler 28 is supported from a sleeve 29 mounted to slide rectilinearly and rotate slightly on the guide bar 27, and movement is given to the sleeve 29 by a bell crank lever fulcrumed at 30 on the arm 24 of the bracket 21, the longer arm 81 of the bell crank lever being pivotally connected at 32 to an arm projecting from the sleeve 29, while the shorter arm 33 of the bell crank lever is provided with a pin 34 engaging the slotted end of alink 35 pivoted at its lower end at 36 to the usual arm 37 extending rearwardly from the, usual controlling rock shaft 38, and held downwardly by the spring 39. In this form fully explained in of filling is called for the shuttle feeler supporting sleeve 29 is moved rearwardly rectilinearly on the. guide bar 27 until it is stopped by the pin 40 at the rearward end of the guide bar. If the shuttle is properly boxed when the lay beats up a trip 41 carried with the bunter 18 striking a depending heel 42 on the shuttle feeler support will throw the bunter 18 into position so that it will strike the nose of the dog 15 and thus operate the transferrer 10 to effect the filling replenishment. If, however, the shuttle is improperly boxed the rearward movement of the shuttle feeler will be restrained by contact with the shuttle, the trip 41 will not reach the heel 42, the bunter 18 not be swung into position to strike the dog and its support will be pushed forwardly by the shuttle on the guide bar 27 and there will be no actuation of the transferrer.

The present invention is concerned as already stated with means to prevent the transfer of thefilling carrier taking place when the filling carrier is improperly positioned' by the feeder or hopper'for transfer. As fully explained in the patent to F. G. and III. Cobb No. 780,266 granted January 7, 1905, should the hopper orfeeder fail properly to present a filling carrier in accurate position for transfer the transferrer upon the next operation of the replenishing mechanism would improperly engage the 'ure it for some of the adjacent mechanism. 'This undesirable reconsequently,

15, and the shuttle feeler forwardly projecting arms 45 provided with horizontally alined hearings in which is mounted a shaft 46. A helical spring 47 surrounds the shaft and is secured at one of its ends to one of the arms 45 and at the v other of its ends to a collar 48adjustably secured to the shaft 46, A catch 49 is clamped to the inner end of the shaft 46 and provided with a hooked rearward end. The parts are so arranged and adjusted that the spring 47 normally acts to maintain the catch 49 elevated with'its hooked end out of of the hopper stand-4, and this bracket has the path of the shuttle feeler supporting v sleeve 29 while if the shaft 46 be rocked to move the catch 49 downwardly it will be brought into the path of the. said sleeve and restrain the movement ofthe shuttle feeler, preventing the operation of the transferrer just as would be done if the movement of the shuttle feeler were restrained by an improperly boxedshuttle. The other end of the shaft 46 is provided with a depending finger 50. A slide bar 51 rests upon the hub of the transferrer and is pivotally secured at 52 to the detent pawl 11. If now.

a filling carrier be brought into proper position for transfer the detent pawl 11 will be firmly seated in a notch in the ratchet wheel 7 and the slide bar 51 will not move the depending finger 50; if however, the filling feeder fails to move to a position properly to position a filling carrier for-transfer then .7

the detentpawl 11 will not be seated firmly in a notch in the ratchet wheel 7, but will be left in a more or less forward position, and the slide bar 51 will be moved forwardly rocking the shaft 46 and depressing the catch 49 into the path of the shuttle feeler support 29. Thus,,it will be seen that this will prevent transfer taking place,'and thus the object of the invention will be secured. v

The invention thus presents a means rendered active by the hopper orfeeder when improperly positioned for the transfer of a filling carrier to restrain the movement of the horizontal shuttle feeler, and thus to prevent the operation of the transferrer.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:
